Coronavirus government response updates: Trump claims to have worn mask, but only off camera

(WASHINGTON) -- President Donald Trump travels to the election battleground state of Michigan to visit a Ford plant converted to make ventilators -- and it's an open question whether he'll wear a mask as everyone else who works or visits there is required to do by law.

Michigan's Democratic attorney general, Dana Nessel, said on CNN this morning that while she won't try to stop Trump, she might take action against companies and other facilities that permit him to do so and possibly block future visits.

"Well, I don't know, we’re gonna look at it," Trump said when asked as he left the White House.

When he eventually toured the plant, he wasn't wearing a mask when speaking with Ford officials -- at a distance -- but then told reporters he had worn one earlier, out of their sight and camera-range.

He said he "didn't want to give the press the pleasure of seeing it."

"I was given a choice" about whether to wear one, Trump said, and when asked about what message he was sending, he responded, "I think it sets an example both ways."

The White House is playing down new findings from Columbia University researchers that 36,000 lives would have been saved had Trump and governors acted a week earlier in March to impose social distancing and other restrictions -- and that a vast majority of the nation's deaths -- some 83 percent -- would have been avoided if stay-at-home limits had been put in place two weeks earlier.

And as the U.S. death toll approaches 100,000 as the nation heads into Memorial Day weekend, House Speaker Nancy Pelosi and Senate Majority Leader Chuck Schumer have sent a letter to President Trump calling on him to order all U.S. flags on government buildings lowered to half-staff that "sad day of reckoning."

Here are Thursday's most significant developments in Washington so far:

President Trump leaves the White House again -- this time to tour a Ford plant, converted to making ventilators, in Ypsilanti, Michigan -- his third visit to a 2020 election battleground state in the past couple of weeks following trips to Pennsylvania and Arizona.

It's unclear whether he'll wear a mask as company rules and Michigan law require him to do.

The state's Democratic attorney general said she won't try to block Trump if he doesn't, but said she might take action against companies and other organizations that allow him to go without a mask and might try to stop future visits.

When asked on Tuesday about whether he would wear a mask, Trump said it depends on how close he comes to other people.

"Well, I don't know, we’re gonna look at it," Trump said when asked as he left the White House Thursday. "A lot of people have asked me that question. I want to get our country back to normal. I want to normalize."

Ford officials have indicated they will let hm bend the rules and go without a mask if he chooses.

Vice President Mike Pence, who wore a mask in similar setting after being criticized for not doing so, did not wear a mask at a Florida burger joint Wednesday during a photo op to highlight restaurants starting to reopen in that state.

WH plays down findings earlier action would have saved 36K lives

The White House, asked Thursday morning about new findings from Columbia University researchers that had the U.S. begun imposing restrictions one week earlier in March, 36,000 lives would have been saved and 54,000 if they'd been imposed two weeks earlier, pointed a finger at China.

“What would have saved lives is if China had been transparent and the World Health Organization had fulfilled its mission,” White House deputy press secretary Judd Deere said in a statement responding to a report in The New York Times.

“What did save American lives is the bold leadership of President Trump, including the early travel restrictions when we had no idea the true level of asymptotic spread and the greatest mobilization of the private sector since World War II to deliver critical supplies to states in need and ramp up testing across the country that has placed us on a responsible path to reopen our country,” he said.

Additionally, a White House official said the “success” of responding to COVID-19 “has been built on the federal-state partnership, not a federal government coming in and telling governors and mayors what decisions to make for their communities when a bureaucrat in Washington has [no] idea what is best for them.”

“We made the best decisions possible for the health and safety of the American people with the information we had at that time,” the official said. “We aren’t looking back. We are moving forward.”

As Memorial Day nears, and with the U.S. death toll now over 93,000 and the Centers for Disease Control and Prevention estimating it will reach 100,000 by the end of the month, House Speaker Nancy Pelosi and Senate Minority Leader Chuck Schumer have sent a letter to President Trump requesting he order flags on all public buildings lowered "on the sad day of reckoning."

Here is the text of their letter:

Dear Mr. President:

This weekend, we will observe Memorial Day an occasion of great importance as we honor the men and women who were willing to make the ultimate sacrifice for our country. We will always carry their memory in our hearts. We reserve Monday to give special remembrance to them.

As we pay our respects to them, sadly, our country mourns the deaths of nearly 100,000 Americans from COVID-19. Our hearts are broken over this great loss and our prayers are with their families.

Respectful of them and the loss to our country, we are writing to request that you order flags to be flown at half staff on all public buildings in our country on the sad day of reckoning when we reach 100,000 deaths. It would serve as a national expression of grief so needed by everyone in our country.
